Legionella Compliance in Schools

Safeguarding Health Through Proactive Measures: Legionella bacteria, responsible for Legionnaires’ disease, pose serious health risks if not properly managed. Schools, with their extensive water systems and periodic closures, can be particularly vulnerable. Ensuring compliance with Legionella control measures is not just a legal obligation but a critical step in protecting the well-being of students, staff, and visitors.

Understanding the Risk

Legionella thrives in stagnant or slowly moving water, especially at temperatures between 20°C and 45°C. Showers, taps, water tanks, and cooling systems can become breeding grounds if not regularly maintained. The risk is heightened during school holidays when water systems are infrequently used.

Legal Responsibilities

In the UK, schools must comply with the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health (COSHH) Regulations 2002. Duty holders—often headteachers, school governors, or facilities managers—are legally required to assess and manage the risk of Legionella.

Key Compliance Measures

1. Risk Assessment: Conduct a thorough Legionella risk assessment by a competent person to identify potential hazards within the water system.

2. Water Safety Plan: Implement a comprehensive plan detailing control measures like regular flushing of unused outlets, temperature monitoring, and disinfection protocols.

3. Regular Monitoring: Ensure water temperatures are maintained outside the Legionella growth range. Cold water should be below 20°C, and hot water should reach at least 50°C.

4. Training and Awareness: Staff responsible for water system maintenance should receive proper training on Legionella risks and control measures.

5. Record Keeping: Maintain detailed records of risk assessments, water temperature checks, system maintenance, and any remedial actions taken.

Addressing Holiday Periods

Extended school holidays can increase Legionella risk due to stagnant water. Schools should implement flushing regimes during closures and consider professional water sampling before reopening.

Final Thoughts

Legionella compliance in schools is an ongoing responsibility that requires diligence, routine checks, and staff training. By following legal guidelines and maintaining proactive water management practices, schools can create a safe environment, ensuring the health and safety of all occupants.
